Abstract
An orthopaedic prosthesis system for replacement of an articulating portion of a long bone includes a sleeve, a stem, and a neck. The sleeve has an outer bone engagement surface and includes opposed proximal and distal female taper regions. The stem has a distal end for fixation within a long bone and a proximal end including a male taper region engaged with the distal female taper of the sleeve. The neck has a taper post that engages the proximal taper of the sleeve. Both the neck and the sleeve may define axial bores, the axial bore in the sleeve communicating with and being generally coaxial with the two opposed female tapers, and the neck axial bore extending through the taper post. A connecting element can engage the stem, pass through the axial bore in the sleeve, extend into the axial bore in the neck taper post, and engage the neck.
